Ashcroft 94582XLL Pressure Gauge 0-100 Psi 2.5in Lower Mount

Product Description

The ASHCROFT 94582XLL is an analog industrial pressure gauge designed for monitoring system pressure in commercial and industrial applications. The gauge features a 2.5-inch dial with a 0 to 100 psi range and delivers 1% of scale accuracy, making it suitable for processes where reliable pressure readings are critical. The stainless steel case (304/316 grade) protects the internals in demanding environments, while the polycarbonate lens resists impact. The Bourdon tube is 316 stainless steel, and wetted parts are bronze. Connection is via a 1/4-inch MNPT lower-mount fitting. Plumbers, pipefitters, HVAC technicians, and industrial maintenance professionals install this gauge on piping systems, pressure vessels, and mechanical equipment.

The 94582XLL is suited for residential and commercial mechanical systems, industrial process piping, and general-purpose pressure monitoring where a dry (non-liquid-filled) gauge is specified. The lower-mount MNPT connection allows direct installation into standard 1/4-inch NPT ports on pumps, manifolds, compressors, and pressure lines. The gauge carries certifications including CRN, IP54, IP65/NEMA 4, PED, and RoHS, making it appropriate for installations where environmental ingress protection or regulatory compliance is required.

Key Features

• 0 to 100 psi range with 1% of scale accuracy for reliable process monitoring
• 2.5-inch analog dial for easy reading at a distance
• 304/316 stainless steel case for corrosion resistance in harsh environments
• 316 stainless steel Bourdon tube with bronze wetted parts
• Dry (no liquid fill) construction for standard pressure applications
• Certified to CRN, IP54, IP65/NEMA 4, PED, and RoHS standards

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for industrial and commercial piping systems with a standard 1/4-inch MNPT lower-mount port.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians. Depressurize and isolate the system before removing an existing gauge or installing this unit. Apply appropriate thread sealant to the MNPT fitting per local plumbing codes; do not overtighten, as this can stress the gauge socket. Verify that the system pressure range does not exceed the gauge maximum before returning the system to service.
